I received “Just testing this out… - Jamie”. But did not get anything containing “I can see in the Admin interface that your emails are going out w/o bouncing. Let me know in a DM if this is not the case.”

I have tried several email addresses and all failed to receive any emails from this forum. Both emails were on domain phor.net, which is run by Endurance hosting and forwards to my Gmail. In 20 years, every email I have tried through this approach worked, this forum is the first time I could not get emails.

Then I tried G Suite email address and it worked.

Can you please tell me which mail service you are using (Mailgun, Mandrill, etc.)? I want to investigate more because I also run a Discourse server.
